Super Sock Snake
Knit a long tube with a toe at each end, then snip to separate them and add cuffs and afterthought heels.
Photos are added to walk you through the process.
And if your nerve fails you and you can’t bear to take scissors to your knitting you could always turn it into a skinny scarf or graft the ends together to make a cowl - win win!
